BOOKING-CHAIR.

Specification of Letters Patent N o. 1,531, dated March 311, 1840.

T0 all whom t may concern Be it known that I, SAMUEL H. BEAN, of thccity and county of Philadelphia and State of Pennsylvania, have inventeda new and useful Improvement in Rocking-Chairs, which is described asfollows, reference being had to the annexed drawings of the same, makingpart of this specification.

The principal feature of this invention and impro-vement consists inmaking the seat and stool of the chair in two parts, so that while thestool remains stationary, the seat is made to rock on the top of it,thus doing away with the long and cumbersome rockers on the commonchair, which occupy a great deal of room and are very destructive tocarpets, and which also ren ders the back of this improved chair sus`ceptible of being fixed in a reclining posi tion at any angle to suitthe wishes of the sitter, and at the same time rendered perfectly securefrom being thrown off the stool.

Figure 1 is a perspective view of the chair. Fig. 2 is a perspectiveview of one of the sliding lock plates and one of the notched hangingplates.

The stool A is about 18 inches high and about the length and breadth ofthe common rocking chair, is horizontal on top, has four legs and restsstationary on the floor. The undersides of the side pieces o-f the seatB are made rounding or rocker shaped, so as to rock on the top, orhorizontal part of the stool, and extend down outside so as to formguards C C, which embrace the sides of the stool and prevent the seatfrom having any lateral movement thereon. It is attached to 'andprevented from being thrown off the stool by four hanging metallicplates D D D D, whose upper ends are suspended from the inside of theseat frame by pins inserted horizontally therein and whose lower endspass loosely through oblong slots or niortises extending verticallythrough the side pieces of the top of the stool, having shoulders orstops projecting from the sides of said plates, near their lower ends,to catch against the undersides of the stool-top to prevent the seatfrom being thrown too far back or forward, or from being disengaged fromthe seat, and likewise to keep the rockers of the seat in theirproperp'ositions on the top of the stool. Notches are made in the edgesof said hanging plates to admit two sliding lock plates E E, one on eachside, which hold the seat in any required position, which plates slideagainst or along the underside of the side pieces of the stool beingperforated with oblong mortises of sutlicient length and breadth toallow the requisite movement over the shanks of screws, over which theymove back and forth, said screws being screwed into the underside of thetop of the stool, with the heads below the sliding plates on which headsthe plates rest. Said sliding plates being also perforated with oblongmortises to allow the hanging plat/es to pass through them and made ofsufiicient length to allow the plates to move backward and forward overthem. Handles F project horizontally1 from the outer edges of .the lockplates which can be reached by the sitter to enable him to alter theangle of his seat while seated. Plates with oblong mortises in them,

Vthrough which the suspended notched plates pass are screwed to theunderside of the stool to prevent the wearing of the wood.

In some cases the bottom of the seat may be made straight and the top ofthe stool convex or rocker shaped. In other cases the seat and stool mayboth be made slightly convex, the principle, however, as beforedescribed, remaining the same.

What I claim as my invention, and desire to secure by Letters Patent,consists in 1. Making the seat and stool of the chair in two parts, sothat the seat shall rock on the top of the stool, instead of having theparts permanently united, with rockers on the legs of the stool asheretofore.

2. And also the mode of connecting t0- gether the seat and stool by thevertical plates attached to the seat passing through the stool withshoulders projecting from the sides thereof which catch against theunderside of the stool when the seat is rocked to or fro.

3. And likewise the m anner of reclining th e back of the seat at anyangle required by the lock plates and notches in the hanging plateswhich receive them as before described.
